ATTACHMENT F'QR WHEELS OF SULKY PLOWS.

SPECIFICATION forming part of Letters Patent No. 725,241, dated April14, 1903.

Application filed October 11, 1902, Serial No. 126,890. (No model.)

To (LZZ whom it may concern:

Be it known that I, CHARLES ALEXANDER GLASS, a citizen of the UnitedStates, residing at Goddard, in the county of Sedgwick and State ofKansas, have invented a new and useful Attachment for Wheels of Sulky-Plows, of which the following is a specification. This invention relatesto an improved attachmeut for the wheels of sulkyplows whereby when theaxle-stubs and the boxes of the wheels become worn the slack may bereadily taken up, so that the wheels'shall be caused to run steady.

. The invention contemplates, furthermore, a device whereby the strainon the wheel caused by the thrust of the plow urging the wheel in thedirection of the land side of the furrow shall be balanced by means of asupporting wheel or pulley at the top of the furrow-wheel against suchstrain, thus preventing the said furrow-wheel from binding in the hub,and hence reducing friction and draft and increasing the life of the boxand spindle.

My invention thus may be said to consist in a small wheel, pulley, orrevoluble member supported by the frame of the plow structure in such amanner as to have the neces sary range of adjustment with relation tothe rim of the furrow-wheel.

pulley or revoluble member which is intended to cooperate with and tosupport .the rim of the furrow-wheel.

which myinvention resides may be built into the frame of the machine,or, in other words,

the said frame may be specially constructed with a view to receiving thesaid revoluble member as a part thereof; but by my present invention Ialso provide a frame or supporting device for the said revoluble memberwhich shall be capable of being attached to practically any sulky-plowor riding-plow which at the present time is in general use,- my objectbeing to provide a supporting and adjusting device by means of which therevoluble member or pulley which forms the essence of my invention maybe properly adjusted with relation to the furrow-wheel of This resultmay be attained in a number of different ways.

In the manufacture of new plows the said revoluble member in manner thatthe main and essential object of my invention shall be easily, simply,and

satisfactorily attained.

; My invention therefore maybe said to consist, specifically, first, inthe combination,with the furrow-wheel of a plow, of a bearingwheel,pulley, or revoluble member disposed to enable the upper inner edge ofthe rim of the furrow-wheel to resist the thrust of the plow urging thewheel in the direction of the land side of the furrow; second, in theimproved means whereby such pulley or revoluble member may be connectedwith or attached to the frame of any ordinary sulkyplow in operativeposition, as will be hereinafter fully described, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is an edge view of a wheel and aportion of the The, portion of the axle shown at at is provided with theusual stub 5, upon which the wheel is-journaled, the axle itself beingthe ordinary crank-axle usually employed in sulky or riding plows.

A clip 6, mounted upon the axle 4 closely "adjacent to the stub 5, iscomposed of two members 7 7, each having a rounded portion 8, wherebythe said members are fitted to embrace the axle and to be firmly securedthereon bymeans of connecting-bolts 9. An additional bolt or connectingmember 10 near the upper end of the clip serves for the attachment of anarm 11, which may be tilted to various points of adjustment, as will bereadily understood. The outer end of the arm 11 is provided with a slot12 for the reception of a bolt 13, carrying a frame or bracket 14:,having suitable means, such as a pin or spindle 15, whereby a pulley orrevoluble member 16 is journaled to said. frame. In the accompanyingdrawings the frame 14 has been illustrated as being simply an L- shapedbracket; but I desire it to be understood that any other suitable andconvenient form of frame may be used.

It will be seen from the foregoing that the clip 6 is adjustable withrelation to the axle 4.; but the arm 11 is capable of being adjustedlaterally with relation to the clip, its normal disposition beingpractically parallel to the wheel, although, as already stated, byadjusting the clip 6 it may be tilted in the direction of the wheel.Finally the bracket 14, carrying the revoluble member 16, is adjustablenot only radially with relation to the wheel, but also pivotally to itspoint of attachment, so that it may be conveniently and very easilyadjusted to support the edge of the rim of the wheel at any point ofsaid rim and in either a-radial or in an approximately tangentialrelation to said rim should it be desired to so adjust it.

The operation of the invention will be very readily understood. When theplow, of which the furrow-wheel 1 is a member, is in operation, thestrain or thrust exercised upon the wheel in the direction of the landside of the furrow will be counteracted by the revoluble member 16,which is adjusted to support the opposite edge of the rim at thediametrically opposite side of the wheel, as will be very obvious byreference to the drawings. Excessive strain and wear upon the hub andaxle are thereby avoided, and the plow is consequently caused to runmore smoothly and with lighter draft.

By the employment of this improved device frictional wear upon the huband axle becomes very much reduced and the draft required to operate theplow proportionately lightened. Such slack as may be occasioned by wearprevious to the attachment of my invention may be taken up andcompensated for and a wheel already considerably worn will be enabled torun with a steadiness which cannot be attained by the use of washers forthe purpose of taking up thewear.

I have described in the foregoing a very simple and therefore apreferable form of my invention; but I would desireit to be understoodthat I do not limit myself to the exact structural details herein shown,but reserve to myself the right to any changes, alterations, andmodifications which may be resorted to without departing from the spiritand scope of my invention or detracting from the utility thereof.

It will also be understood that the device herein specifically describedis capable of being attached to and used in connection with practicallyany riding-plow in existence, the range of adjustment of the pulley orrevoluble member 16 with relation to the furrow-wheel being suflicientlyextensive to enable the device to be used in connection with framestructures of widely-varying patterns. When the device is applied toplows newly constructed, it will be possible to greatly simplify thesupporting means of the pulley without departing in any degree from thespirit of myinvention.

Having thus fully described my invention, what I claim is- 1. A deviceof the class described, comprising a wheel, a revoluble member,supporting means for the latter, and means for adjusting the sameradially with relation to the wheel.

2. A device of the class described, com prising a wheel, a revolublemember, means for supporting said revoluble member,and means foradjusting said revoluble member radially and tangentially with relationto the wheel.

3. A device of the class described, comprising a wheel, a revolublemember and a supporting-frame for said revoluble member having pivotaland slidable adjustment.

4.. A device of the class described, comprising a wheel, a crank-axle, aclip upon the latter, and an arm connected pivotally with said clip andsupporting a revoluble member adapted to engage the edge of the rim ofthe wheel.

5. A device of the class described, comprising a wheel, acrank-axle, anarm supporting a revoluble member adapted to engage the edge of the rimof the wheel, and means for connecting said arm with the axle,adjustably, to regulate the position of the revoluble member, withrelation to the rim of the wheel.

6. A device of the class described, comprisinga wheel, a crank-axle,aclip upon'said axle, an arm mounted between the members of said clipupon a single bolt upon which it may have pivotal adjustment, and arevoluble member supported by said arm and adapted to engage the edge ofthe rim of the wheel.

7. A device of the class described, comprising a wheel,a crank-axle,aclip upon said axle, an arm connected adj ustably with said clip, aframe having pivotal and slidable connection with said arm, and arevoluble member journaled in said frame and adapted to engage the edgeof the rim of the wheel.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

CHARLES ALEXANDER GLASS.
